现将参考附图详细描述各种实施例，其作为本公开的示例性示例而提供，以使得本领域技术人员能够实现本公开。值得注意的是，以下附图和示例并不意味着限制本公开的范围。在使用已知的组件(或方法或过程)可以部分或全部实现本公开的特定元件的情况下，将仅描述对理解本公开 所需要的这种已知组件(或方法或过程)的那些部分，并且这种已知组件的其它部分的详细描述将被省略以便不会混淆本公开。进一步地，各种实施例通过说明的方式包含与在此涉及的组件等同的现在和未来已知的等同物。
在本公开的描述中，术语“上”、“之上”、“下”、“之下”、“顶”、“底”、“之间”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本公开和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本公开的限制。此外，当元件或层被称为在另一元件或层“上”时，它可以直接在该另一元件或层上，或者可以存在中间的元件或层；同样，当元件或层被称为在另一元件或层“下”时，它可以直接在该另一元件或层下，或者可以存在至少一个中间的元件或层；当元件或层被称为在两元件或两层“之间”时，其可以为该两元件或两层之间的唯一的元件或层，或者可以存在一个以上的中间元件或层。

在液晶显示装置中，黑矩阵(BM)可以设置在与阵列基板相对设置的基板(在本文的其他地方也称对置基板)上并且分别沿行方向和列方向布置，用于将不同行的像素和不同列的像素分割开以防止混色以及用于遮挡位于阵列基板上的信号线或电子器件等。然而，在基于COA的曲面显示装置中，对置基板和阵列基板被例如围绕列方向弯曲。在这种情况下，行方向上的黑矩阵随着对置基板一起弯曲，而列方向上的黑矩阵由于对置基板的弯曲而产生不同程度的变形和/或偏移，例如，一部分黑矩阵向左偏移到左侧像素中，另一部分黑矩阵向右侧偏移到右侧像素中，因此带来混 色、色偏、漏光等问题。为了避免由于黑矩阵的变形和/或偏移导致的混色、色偏、漏光等问题，在制备曲面显示装置时，例如可以不在列方向上设置黑矩阵，而通过采用设置在阵列基板上的沿列方向延伸的信号线将不同列的像素分开。图1示出了曲面显示装置的黑矩阵的布置的示意图。在图1中，黑矩阵101被布置在行方向上，即沿行方向上延伸，而列方向上没有布置黑矩阵。
在COA技术中，在阵列基板上制作薄膜晶体管后，直接制作彩色滤光层，然后将绝缘层、像素电极等其他膜层制作在彩色滤光层的上方。图2示出了基于COA的阵列基板的横截面示意图。在图2所示的配置中，为了使得能够向像素电极201传输信号，需要在阵列基板中设置多个通孔202，以便电连接像素电极201和薄膜晶体管203。通常，彩色滤光层204的厚度远大于阵列基板上其他膜层(例如像素电极201、绝缘层205等)的厚度，因此当彩色滤光层制作在阵列基板上时，形成的通孔202具有较大的深度(相比于彩色滤光层制作在对置基板上)。如此一来，在进行真空处理时，很难将通孔中的空气完全排除出去。当将阵列基板和对置基板对盒并填充液晶后，残留在通孔中的空气形成小气泡进入液晶层。在对显示面板进行密封烘烤(seal oven)工艺中，这些小气泡可以在液晶层中移动，使得小气泡聚集成大气泡。这种大气泡在密封烘烤时很难从液晶层中排除出去，因此严重影响显示面板的显示效果。
需要说明的是，在本文中，术语“像素”是用于显示图像的基本功能单元，其包括用于显示的功能区域和未用于显示的非功能区域，该功能区域可以包括像素电极、面对该像素电极的公共电极部分、位于像素电极和公共电极相应部分之间的液晶层部分、以及相应的滤光区域(红色、绿色或蓝色)。该非功能区域包括诸如薄膜晶体管、数据线、栅极线以及黑矩阵等。术语“像素区域”或“像素所在的区域”表示像素所占有的区域。然而，为了方便，在本文的一些部分中可以不明确区分“像素”、“像素区域”和“像素所在的区域”。在本文中，曲面显示面板的开口区域表示像素的功能区域。
本公开的实施例提供一种用于曲面显示面板的基板，通过在该基板的衬底基板上形成的阻挡部，该阻挡部在衬底基板上的正投影位于曲面显示面板的开口区域在衬底基板上正投影区域内，来阻碍气泡在液晶层中的移动，从而能够阻碍小气泡汇聚成大气泡。图3a-3d示出了根据本公开的实施例提供的用于曲面显示面板的基板平面示意图。如图3a-3d所示，该基板可以包括弯曲的第一衬底基板301；位于第一衬底基板301上并沿大致平行于第一衬底基板301的曲边方向延伸的条状黑矩阵302；以及位于第一衬底基板301上的阻挡部303，阻挡部303在第一衬底基板301上的正投影位于曲面显示面板的开口区域304在第一衬底基板301上的正投影区域内。如图3a-3d所示，开口区域304可以示意性地表示为两条虚线之间的区域，该区域通常对应于曲面显示面板的像素内区域。在本公开的实施例中，该阻挡部303能够阻碍曲面显示面板的液晶层中的气泡的移动。
在本公开的实施例中，“条状黑矩阵302沿大致平行于第一衬底基板301的曲边方向延伸”可以理解为条状黑矩阵302沿大致平行于第一衬底基板301的曲边方向连续延伸，也可以理解为条状黑矩阵沿大致平行于第一衬底基板301的曲边方向延伸的过程中具有一个或多个断点。
在本文描述的实施例中，通过在基板上形成阻挡部303，使得阻挡部303在条状黑矩阵302的延伸方向上(即气泡的潜在移动路径上，如图3a-3d中的箭头所示)形成障碍，这可以有效地阻碍气泡在液晶层中的移动，从而有效地阻碍在密封烘烤工艺中小气泡因移动而汇聚成大气泡进而影响显示面板的显示效果。此外，将阻挡部设置在像素所在的区域内而不是相邻像素区域之间，可以避免在曲面显示面板中由于基板的弯曲而造成的混色、色偏以及漏光等问题。
在本文描述的实施例中，像素可以包括红色子像素、绿色子像素和蓝色子像素，阻挡部303在第一衬底基板301上的正投影可以位于红色子像素、绿色子像素和蓝色子像素中的任一种或多种子像素在第一衬底基板上的正投影内。然而，可以理解，考虑到由本公开提供的基板形成的显示面板的开口率等因素，在可选的实施例中，可以使阻挡部303在第一衬底基 板301上的正投影仅位于一种子像素在第一衬底基板301上的正投影区域内。通过这种配置，一方面能够对液晶层中的气泡起到阻碍作用，另一方面也不会明显影响产品的开口率。
考虑到红色子像素区域相比于绿色子像素和蓝色子像素在显示面板中具有更高的光透过率，在一个实施例中，可以将阻挡部303设置为使其在第一衬底基板301上的正投影位于红色子像素在第一衬底基板301上的正投影区域内，即，可以将遮挡部303设置在第一衬底基板的对应于红色子像素区域的区域内。在这种配置中，可减少阻挡部对产品的光透过率的潜在影响，而且也不明显影响产品的色域、色温等特性。
在一个实施例中，阻挡部可以由与条状黑矩阵相同的材料形成。在这种配置中，在制作基板时，阻挡部可以与条状黑矩阵一体或接触地形成，因此可以简化制作工艺。如图3a所示，阻挡部303可以包括位于条状黑矩阵302的沿条状黑矩阵302的延伸方向的侧面上的凸起；如图3b所示，阻挡部303也可以包括位于条状黑矩阵302的沿条状黑矩阵302的延伸方向的侧面上的凹陷；如图3c所示，阻挡部303还可以包括连接相邻两个条状黑矩阵302的连接部；如图3d所示，阻挡部303还包括位于相邻条状黑矩阵302之间的与条状黑矩阵302隔离的岛。可以理解，在本公开的实施例中，阻挡部也可以包括凸起、凹陷和连接部中的多种的组合。关于阻挡部的位置和形状的其他实施例也是可行的。
本公开的实施例还提供一种曲面显示面板。图4示出了根据本公开的实施例提供的曲面显示面板的示意性截面图。需要说明的是，图4仅仅是为了示意性示出曲面显示面板的各个组件之间的相对位置关系，并且为了简便起见，在图4中将曲面显示面板绘制成了平面形式。在实际的产品中，图4中的阵列基板和与阵列基板相对设置的基板(在本文中也称为对置基板)都被弯曲成具有一定的弧度。
如图4所示，曲面显示面板可以包括阵列基板401；与阵列基板401相对设置的对置基板402；以及设置在阵列基板401和对置基板402之间的液晶层403。
在该实施例中，对置基板402可以采用图3a-3d所示的实施例中的基板，因此在本文中对图3a-3d所示的实施例中的基板的解释说明也适于本实施例。
如图4所示，对置基板402可以包括被弯曲的第一衬底基板301；位于第一衬底基板301上并沿大致平行于第一衬底基板301的曲边方向延伸的条状黑矩阵(参见图3a-3d中的302)；以及位于第一衬底基板301上的阻挡部303，其中该阻挡部303在第一衬底基板301上的正投影位于曲面显示面板的开口区域304在第一衬底基板301上的正投影区域内。该阻挡部303可以在条状黑矩阵的延伸方向上(即气泡的潜在移动路径上，如图3a-3d中的箭头所示)形成障碍，因此可以阻碍液晶中气泡的移动和汇聚。
此外，应当理解，在本公开的实施例中，对置基板402还可以包括位于条状黑矩阵上的保护层(Over Coat，OC)404和公共电极层405。
在制备对置基板402的过程中，首先可以第一衬底基板301上形成黑色色阻层；其次可以在一次构图工艺中同时形成条状黑矩阵302和阻挡部303，阻挡部303的形状可以根据具体产品的需求来选择，例如，可以是条状黑矩阵302上的凹陷或凸起，还可以是连接两个条状黑矩阵302的连接部或者是位于两个条状黑矩阵302之间并与所述条状黑矩阵隔离的岛；然后，可以依次形成公共电极ITO层405和隔垫物层等。
阵列基板401可以包括与第一衬底基板301具有相同的弯曲方向的第二衬底基板406；位于第二衬底基板406上的薄膜晶体管407；以及位于第二衬底基板406上的彼此交叉的第一信号线(例如栅极信号线)501和第二信号线(例如数据信号线)502(如图5b所示)，其中第一信号线(例如栅极信号线)501(在行方向上，如图5b所示)在第一衬底基板301上的正投影位于条状黑矩阵302(如图5a所示)在第一衬底基板301上的正投影区域内，即，第二衬底基板406上的第一信号线501的位置与第一衬底基板301上的条状黑矩阵302的位置在垂直于第一和第二衬底基板的方向上相对应。相应地，第二信号线502在第一衬底基板301上的正投影位于相邻两列开口区域304在第一衬底基板301上的正投影之间。
通过这种配置，可以通过条状黑矩阵302将不同行的像素分割开来，并且可以通过例如数据信号线将不同列的像素分割开来。可以理解，在一个或多个实施例中，栅极信号线(第一信号线)501和数据信号线(第二信号线)502的位置也可以互换，使得数据信号线502的位置与条状黑矩阵301的位置相对应。还应当理解，根据实际产品的需要，条状黑矩阵302的位置也可以与除栅极信号线501和数据信号线502之外的其他信号线(如果存在的话)相对应。
阵列基板402还可以包括位于第二衬底基板406上的彩色滤光层，该彩色滤光层中形成有到达薄膜晶体管的源极或漏极的过孔。
在一个实施例中，彩色滤光层可以包括红色滤光区域、绿色滤光区域和蓝色滤光区域。应当理解，红色滤光区域、绿色滤光区域和蓝色滤光区域分别对应于曲面显示面板的红色子像素(R)、绿色子像素(G)和蓝色子像素(B)。在该实施例中，阻挡部303在第一衬底基板301上的正投影位于红色滤光区域、绿色滤光区域和蓝色滤光区域中的一种滤光区域在第一衬底基板301上的正投影区域内。在一个可选的实施例中，阻挡部303在第一衬底基板301上的正投影位于红色滤光区域在第一衬底基板301上的正投影区域内，即阻挡部303位于第一衬底基板301上的与红色滤光区域相对应的位置。这种配置使得阻挡部303不会明显影响曲面显示面板的透过率，并能够阻碍气泡由于在曲面显示面板的液晶层中的移动而汇聚成大气泡。
图5a示出在本公开的实施例中对置基板上的条状黑矩阵302和阻挡部303的位置关系的示意图，5b示出在本公开的实施例中阵列基板上的彩色滤光区域、栅极信号线501和数据信号线502之间的位置关系的示意图。图5a中虚线503表示对置基板上的与图5b中的阵列基板上数据信号线502相对应的位置，图5b中的虚线504表示阵列基板上的与图5a中的对置基板上阻挡部303相对应的位置。如图5a和5b所示，条状黑矩阵302的延伸方向基本上平行于栅极信号线501，阻挡部303设置在与彩色滤光区域/彩色子像素RGB(例如红色滤光区域/红色子像素R)的区域内。
在本公开的实施例提供的曲面显示面板中，通过在第一衬底基板301上设置阻挡部303，使得阻挡部303在条状黑矩阵302的延伸方向上(即气泡的潜在移动路径上)形成障碍，可以有效地阻碍在密封烘烤工艺中小气泡汇聚成大气泡而影响显示面板的显示效果。此外，由于阻挡部303位于曲面显示面板的开口区域304在第一衬底基板301上的正投影区域内而不是相邻开口区域304在第一衬底基板301上的正投影之间，因此在将基板弯曲形成基板时不会造成混色、色偏或漏光的问题。
本公开的实施例还提供一种曲面显示装置，包括本文所描述的任一种曲面显示面板。由于本实施例提供的曲面显示装置可以采用本文描述的曲面显示面板，因此在本文中对曲面显示面板进行的解释说明也适于本实施例中的曲面显示装置，在本实施例中不做重复说明。
同样，在本实施例提供的曲面显示装置中，通过在第一衬底基板301设置阻挡部303，其中阻挡部303位于曲面显示面板的开口区域304在第一衬底基板301上的正投影区域内，使得阻挡部在条状黑矩阵302的延伸方向上(即气泡的潜在移动路径上)形成障碍，这可以有效地阻碍在密封烘烤工艺中小气泡汇聚成大气泡而影响显示面板的显示效果。此外，由于阻挡部位于开口区域304在第一衬底基板301上的正投影区域内而不是相邻的开口区域304在第一衬底基板301上的正投影之间，因此在将基板弯曲形成基板时不会造成混色、色偏或漏光的问题。
以上为了说明和描述的目的提供了实施例的前述描述。其并不旨在是穷举的或者限制本申请。特定实施例的各个元件或特征通常不限于特定的实施例，但是，在合适的情况下，这些元件和特征是可互换的并且可用在所选择的实施例中，即使没有具体示出或描述。同样也可以以许多方式来改变。这种改变不能被认为脱离了本申请，并且所有这些修改都包含在本申请的范围内。
